Can Victor motor controllers be used with the Vex controller?
Yes, the Vex Controller is compatible with the Victor Speed Controller. The Victor control signals (PWM cable) can be connected directly to the Vex Controller Motor Outputs with the proper cable. The sex on the female end of a standard M-F PWM connector must be swapped from female to male which can be done using a 3 pin header or use a M-M PWM Cable.
